Just curious, why would you not have picked the PA Germans, aka the PA
Dutch. I don't think anyone prior to your DNAPrint test would have
surmised that some of us may be harboring ancient "East" Asian content,
such as for my test and for Zach's wife. Going into your DNAPrint test I
think most PA Germans would think they were 100% European. What advance
knowledge did you have which would rule out the PA Germans, aka PA
Dutch.

Also, again, do you consider Mongolia, which is north of and abuts
China, as East Asian for your definition of your East Asian population
group. It seems logical to me that Mongolia would be included. It
certainly would make sense as to how "East" Asian genetic content got
into Europe. It certainly didn't get there in large numbers via modern
Chinese, Korean, or Japanese immigration such that it would show up in
the PA German stock. I think they definitely should be included. As you
know, I have suggested changing the graphic map for the Group
delineations. You said you were going to look into in one email. I just
wanted to see if you agree with those points. If Cambodia and Vietnam
are in then I think definitely Mongolia should be too. And according to
the reference source I found the other day, Mongolia is defined as part
of East Asia.
